Description

Technical Field

[0001] The utility model relates to the technical field of paper cup processing equipment, in particular to an adhesive equipment for the bottom of a paper cup. Background Technique

[0002] A paper cup is a paper container made by mechanically processing and bonding the base paper (white cardboard) made of chemical wood pulp, with an appearance of a cup shape. The paper cups used for frozen foods are waxed and can hold ice cream, jam, butter, etc. The paper cups used for hot drinks are coated with plastic and can withstand temperatures above 90°C and even hold boiling water. The characteristics of paper cups are safety, hygiene, lightness and convenience. They can be used in public places, restaurants, and dining halls and are disposable items.

[0003] The existing adhesive equipment for the bottom of a paper cup is exquisitely designed and can adapt to various differently shaped paper cups. For example, the utility model with the patent number CN211843410U. However, although this device can process paper cups of different shapes, its bonding process has some limitations. When performing the bonding operation, it is usually necessary to heat to soften the glue so that a more firm bond can be formed between the bottom of the cup and the paper cup. This process is crucial for ensuring product quality. However, the above-mentioned device does not have a built-in heating function, which means that without an external heat source, it may not be able to effectively soften the glue. Therefore, this may lead to insecure bonding, and even in extreme cases, the bonding process will completely fail. Content of the Utility Model

[0025] Please refer to Figures 1-7, the present utility model provides a technical solution: an adhesive device for the bottom of a paper cup, including a first housing 2 and a second housing 3. Inside the bottom of the first housing 2, there are several guide rails 12. One of the guide rails 12 is fixed inside the first housing 2, and the other guide rail 12 is fixed outside the second housing 3. On each of the several guide rails 12, there is a sliding groove 17 clamped. On one side of each sliding groove 17 away from the guide rail 12, there are several mounting rings 18. On one side of each mounting ring 18 away from the sliding groove 17, there are several fan blades 13 fixed. Inside the second housing 3, there is a heating wire 11 wound around. Inside the heating wire 11, there is a heat conducting cotton 9. At both the upper and lower ends of the heat conducting cotton 9, at both ends of the second housing 3, there are several heating rings 8. On the side of the heating ring 8, there are several limiting blocks 10 arranged in a ring shape, used to separate the several heating rings 8 and fix them on the first housing 2. The heating ring 8 cooperates with the fan blade 13 to blow air and heat the air, thereby heating the paper cup. The heat generated by the set heating wire 11 is evenly transferred through the heat conducting cotton 9.

[0026] Further, the sliding groove 17, the guide rail 12, and the mounting ring 18 are all circular rings, which is convenient for driving the fan blade 13 to do circular motion.

[0027] Further, between the first housing 2 and the second housing 3, there are several fixing plates 16. On one of the fixing plates 16, there is a motor 15. The output end of the motor 15 is sleeved with a gear 14. One side of the gear 14 is engaged with one side of the sliding groove 17. The fixing plate 16 fixes the first housing 2 and the second housing 3, and at the same time fixes the motor 15 and is convenient for the motor 15 to drive the gear 14 to rotate, thereby pushing the sliding groove 17 to rotate.

[0028] Further, on both the heating wire 11 and the heating ring 8, there is an electric wire 5, used to connect to the power supply to make the heating wire 11 and the heating ring 8 start working.

[0029] Further, at the same position of each heating ring 8, there is an opening. At both ends of the opening, on the heating ring 8, there are electric wires 5 connected respectively, so that the heating ring 8 generates heat.

[0030] Further, the other ends of the electric wires 5 arranged on the heating ring 8 and the heating wire 11 are both connected to a control device 7. And on one side of the operating device, there is a plug 6 to provide power for the device. The operating device is used to control the switch and temperature control of the heating ring 8 and the heating wire 11.

[0031] Further, inside the heat conducting cotton 9, there is an adhesive device body 1, used for the bonding of the paper cup and the cup bottom.

[0032] Working principle: Before use, start the heating ring 8 and heating wire 11 through the control device 7, and set the required temperature through the control device 7. After the heating wire 11 is energized through the wire 5, it generates heat. The heat generated by the heating wire 11 is absorbed by the heat-conducting cotton 9 and evenly transferred to one end of the bonding device body 1. At the same time, after the heating ring 8 is energized, it generates heat. The motor 15 at the bottom of the first housing 2 rotates, driving the gear 14 to rotate. The gear 14 rotates and pushes the chute 17 fixed on the inner side of the first housing 2 to rotate. The chute 17 is pushed by the gear 14 to make a circular motion on the guide rail 12. When the chute 17 rotates, it drives the mounting ring 18 to rotate. A number of fan blades 13 on the mounting ring 18 rotate with the mounting ring 18, pushing the air upward and passing through between a number of heating rings 8. The air is heated by the heating rings 8 and then blown onto the paper cup.

[0033] The heating wire 11 heats the bonding device body 1, and the bottom of the cup is heated through the bonding device body 1. The heating ring 8 cooperates with the fan blades 13 to blow the heated air onto the paper cup and heat the paper cup, so that the upper part and the bottom of the paper cup are heated simultaneously, promoting the softening of the glue and firmly bonding the bottom of the cup.

[0034] It should be noted that: The entire device is controlled by the total control device. Since the devices matched with the control device are common devices and belong to the existing mature technologies, the electrical connection relationship and the specific circuit structure are not described in detail here.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
